My sister had to have the tile flooring in her son's room renewed since something seems to be wrong with how they were installed. She had them installed when my nephew went to college since he wouldn't be able to sleep there while the men were working. It wasn't a pretty sight, and there was dust all over! I hope that I wouldn't have the same problem as her; I think it's too much trouble!
But who knows ... I'll just be keeping my fingers crossed. :D
